Had a connector pin back out on me mid-flight and it changed how I prep harnesses now
I was troubleshooting a intermittent avionics bus error on a King Air last Tuesday at KMEM and found a pin that worked its way loose from a D-sub shell. Now I give every connector a tug test before I close it up and I haven't had that issue since. Anyone else ever deal with pin retention problems on older aircraft?

Oh man, you bet I have. It's the worst feeling pulling a connector apart and seeing that pin just sitting there loose, not even doing its job. I swear, on the older birds like that, the plastic in the shells gets brittle and just stops holding onto the pins tight. I do the same exact tug test now, and I even give a little twist to make sure the retention clip is really biting. It's such a simple thing but it saves you from chasing a ghost in the system for hours. Definitely a habit that sticks with you after you've been burned once.
